Start in a standing position with feet shoulder width apart. Grasp one weight with both hands overhead. Keeping your upper arms steady, lower the weight at the elbows 90 degrees. Flex triceps to bring the weight back up overhead. Make sure to keep shoulders down and back (not hunched) and elbows in line with shoulders. If you are feeling discomfort in elbows, shoulders or wrists, carefully remove the weight and adjust your positioning before continuing.
